PLEASE HELP ME FAST

At the school cafeteria, the cost of one milk is $0.50. The total cost of 5 turkey sandwiches and 4 milks is the same as the total cost of 4 turkey sandwiches and 8 milks.

a. Write an equation that can be used to find the cost of a turkey sandwich. Explain what each expression or value represents in the equation.

b. Use the equation you wrote in part a. to find the cost of a turkey sandwich. Explain how you solved the equation.

Answer 1

t = turkey sandwiches
m = milk

5t + 4m = 4t + 8m
5t - 4t = 8m - 4m
t = 4m

m = .50
sub .50 in for m in your answer above
t = 4m
t = 4(.50)
t = 2.00

lets check....
5t + 4m = 4t + 8m
5(2) + 4(.5) = 4(2) + 8(.5)
10 + 2 = 8 + 4
12 = 12 (correct)

ANSWER : turkey sandwiches are $2.00
